     Creating two iframes that mimics the attention screen behavior on the
     device:
       - the 'dialer' iframe is the attention screen you have when a call is
         in place. it is a green bar, so we copy it as green here too
       - the 'apps' iframe mimics another application that is being run, be it
         dialer, sms, ..., anything that the user might want to trigger during
         a call

     The bug we intent to reproduce here is that in this case, if the user taps
     onto the top of the 'apps', the event fluffing code will in fact redirect
     the event to the 'dialer' iframe. In practice, this is bug 921928 where
     during a call the user wants to place a second call, and while typing the
     phone number, wants to tap onto the 'delete' key to erase a digit, but ends
     tapping and activating the dialer.
